Method for reminding of entering target route

Abstract

A method for reminding of entering a target route is disclosed. First, the method provides a Point of Interest (POI) at a conjunction of the present route and the target route and sets the POI as a basic voice reminding point. Next, the method determines whether the actual distance between the present position and the basic voice reminding point is less than or equal to the voice reminding distance. Then, when the actual distance between the present position and the basic voice reminding point is less than or equal to the voice reminding distance, a voice reminding message is sent out as the reminding of entering the target route correctly.

1. A method for reminding of entering a target route suitable for entering the target route from a present route on a present position, and the method comprising:
 providing a Point of Interest (POI) at a conjunction of the present route and the target route, and setting the POI as a basic voice reminding point, wherein the step of providing the POI at the conjunction of the present route and the target route comprises:
 extracting an electronic map; 
 setting the present route as a first map layer and setting the target route as a second map layer on the electronic map; and 
 obtaining a plurality of intersection points by corresponding the first map layer to the second map layer, and setting one of the intersection points as the conjunction for providing the POI; 
 
 determining whether an actual distance between the present position and the basic voice reminding point is less than or equal to a voice reminding distance; and 
 sending out a reminding message for entering the target route when the actual distance between the present position and the basic voice reminding point is less than or equal to a voice reminding distance. 
 
   
   
     2. The method for reminding of entering the target route of  claim 1 , further comprising when the actual distance between the present position and the basic voice reminding point is greater than the voice reminding distance, continuously determining whether the actual distance between the present position and the basic voice reminding point is less than or equal to the voice reminding distance. 
   
   
     3. The method for reminding of entering the target route of  claim 1 , wherein the present route is a common road and the target route is a highway entrance. 
   
   
     4. The method for reminding of entering the target route of  claim 1 , wherein the present route is a highway and the target route is a highway exit. 
   
   
     5. The method for reminding of entering the target route of  claim 1 , wherein the present position is a position detected by Global Positioning System (GPS) when it is activated. 
   
   
     6. The method for reminding of entering the target route of  claim 1 , wherein the reminding message is a voice reminding message. 
   
   
     7. A method for configuring a Point of Interest (POI) suitable for entering a target route from a present route on a present position through a conjunction, applicable to a mobile device with a GPS, the method comprising the steps of:
 extracting an electronic map; 
 setting the present route as a first map layer and setting the target route as a second map layer on the electronic map; and 
 obtaining a plurality of intersection points by comparing the first map layer with the second map layer, and setting one of the intersection points as the conjunction for configuring the POI. 
 
   
   
     8. The method for configuring the POI of  claim 7 , wherein the conjunction connects both the present route and the target route. 
   
   
     9. The method for configuring the POI of  claim 7 , wherein the present route is a common road or a highway and the target route is a highway entrance or a highway exit. 
   
   
     10. A method for reminding of entering a target route from a present route on a present position, applicable to a mobile device with a GPS (Global Positioning System), the method comprising the steps of:
 providing a POI (Point of Interest) at a conjunction of the present route and the target route, with the POI set as a basic voice reminding point, wherein the step of providing the POI at the conjunction of the present route and the target route comprises:
 extracting an electronic map; 
 setting the present route as a first map layer and setting the target route as a second map layer on the electronic map; and 
 comparing the first map layer with the second map layer to obtain and set one of a plurality of intersection points as the conjunction for providing the POI; 
 
 determining whether an actual distance between the present position and the basic voice reminding point is less than or equal to a voice reminding distance; and 
 sending out a reminding message for entering the target route when the actual distance between the present position and the basic voice reminding point is less than or equal to a voice reminding distance. 
 
   
   
     11. The method for reminding of entering the target route of  claim 10 , further comprising when the actual distance between the present position and the basic voice reminding point is greater than the voice reminding distance, continuously determining whether the actual distance between the present position and the basic voice reminding point is less than or equal to the voice reminding distance. 
   
   
     12. The method for reminding of entering the target route of  claim 10 , wherein the present route is a common road and the target route is a highway entrance. 
   
   
     13. The method for reminding of entering the target route of  claim 10 , wherein the present route is a highway and the target route is a highway exit. 
   
   
     14. The method for reminding of entering the target route of  claim 10 , wherein the present position is a position detected by the GPS when it is activated. 
   
   
     15. The method for reminding of entering the target route of  claim 10 , wherein the reminding message is a voice reminding message. 
   
   
     16. A method for configuring a Point of Interest (POI) suitable for entering a target route from a present route on a present position through a conjunction, applicable to a mobile device with a GPS, the method comprising the steps of:
 extracting an electronic map; 
 setting the present route as a first map layer and setting the target route as a second map layer on the electronic map; and 
 comparing the first map layer with the second map layer to obtain and set one of plurality of intersection points as the conjunction for providing the POI. 
 
   
   
     17. The method for configuring the POI of  claim 16 , wherein the conjunction connects both the present route and the target route. 
   
   
     18. The method for configuring the POI of  claim 16 , wherein the present route is a common road or a highway and the target route is a highway entrance or a highway exit.
